BALL COCK FOR 'USE 'UPON HIGH AND LOW IvRESSURE SYSTEHB.4

Application led February 14, 1924. Serial No. 692,722.

To all whom t may concern.'

Be it known that I, THOMAS W. RYAN, a citizen ofthe United States, and a resident of Concord Junction, county of Middlesex,

State of Massachusetts, have invented an Improvement in Ball Cocks for Use upon High and Low Pressure Systems, of which the following description, in connection with the accompanying drawing, is a specification, like characters on the drawing representing like parts.

This invention relates to improvements in ball-cocks and the general object thereof is to produce a ball-cock having a substantially Silent delivery for the liquid when used either upon high or low pressure systems and which will not unduly restrict the delivery of liquid when used upon low pressure systems.

A further object of the invention is to provide a ball-cock which is adapted for use without modification in all stories of high oiice and apartment buildings.

These and other objects and features of the invention will more fully appear from the following description and the accompanying drawing and will be particularly pointed out in the claims.

In the drawing:

Fig. 1 is a vertical lon itudinal sectional view of an illustrative orm of ball-cock construction embodying the invention, the piston and baille plates being illustrated in elevation, and in which the piston is actuated by a single ball-controlled lever;

Fig. 2 is a sectional view on line 2-2, Fig. 1, looking downwardly;

Fig. 3 is a sectional vlew on line 3 3, Fig. 1, looking downwardly; and,

Fig. 41 is a View, artly in section, of a modified form of ba -cock showing also a com ound leverage for actuating the piston.

T e present invention embodies certain improvements on the construction disclosed in my prior Patent No. 1,163,370 granted December 7, 1915.

The referred form of the invention illustrated 1n Figs. 1, 2 and 3 comprises a casing having a, cylindrical portion 1 provided at its inlet end with external screw threads 2 by which it is adapted to be connected to the usual coupling 3 which is mounted upon the Wall 4- of the tank and is adapted to be connected to an inlet pipe. The casing also is provided with an enthe eductive action of the stream to larged, preferably a spheroidal section 5, having a downwardly curved extension 6 to which is connected a delivery pipe 7 which extends nearly to the bottom of the tank. The casin thus constructed is provlded with a cylindrical chamber 8 and an enlarged outlet chamber 9. Preferably a partit-ion 10 extends transversely through the enlarged portion of the chamber 9 and lts downward extension and together with an upwardly extending boss 11 provides bearings for an enlarged cylindrical portion 12 of the piston 13. The transverse partition 10 also serves to deflect the flow of liquid from the discharge opening andv to cause prevent leakage through the outer bearing.

The casing is also provided with up.- wardly and laterally extending arms 14 in which the pivots 15 of the ball lever 16 are mounted, the ball lever 16 being actuated by the usual ball (not shown) connected to the arm 17 which is adjustably secured to the ball lever 16 byy a setvscrew'18. The ball lever desirably is bifurcated andy the arms thereof connected by a shaft 19 preferably 'having thereupon an antifriction roller 20 which engages'the walls of a horizontal slot 21 in the flattened upper end 22 of the pist0n.y A valve seat 23 is located at the inlet end of the cylindrical portion of the casing and desirably is of the form 'shown comprising a cylindrical I portion which fits tightly within the casing and has at its lower end an outwardly extending conoidal portion which abuts against complementa conoidal walls in the end of the casin washer 24 is interposed between the lower end of the valve seat 23 and the base of the e enlarged portion of the coupling 3 so that when the casing is screwed into the coupling the valve seat will force the washer tightly against its seatin the coupling and provide a tight `oint. The end of the piston 13 is provide with a valve 25 havin a washer 26 which co-operates with the va. ve seat 23. The construction thus described may be and preferabl is substantially identical with that disclose in my prior patent aforesaid. In the construction disclosed in theA prior patent the piston is provided with a series of baille plates alternately dis .osed on opposite sides of the piston with t eir adjacent edges overlapping these baie plates acting to cause the liquid to flow through the cylindrical chamber of the casing in sinuous paths' so thatv the interference. and eddying of the ressure, whileby reason of-A the lesser inter erence of the sinuous currents under low ressure the liquid is permitted to flow witli such substantial freedom that the tank will be iilled in the same time whether employed upon a high pressure or low pressure system.

The object of the present invention is to provide a ball-cock which will be more nearly noiseless in its operation than valves heretofore constructed and also which will be adapted to be emplo ed u lon more wide` 1y varying pressures t an t ose for which previous ball-cocks have been designed.

' The present invention broadl comprises the rovision of a plurality o means for prodiicing currents `of different characters within the cylindrical 'chamber of the ballcock which will co-act to produce a substantiall noiseless and uniform delivery of the liquid under widely diil'erent pressures.

In the eferred construction illustrated in Fig. 1 t e lower portion of the piston 13 rovided with a spiral rib or flange 27 'which desirably slid-ably iits within the casing a-nd a pluarlity of baille plates 28 which extend from the piston in perpendicular re' lation to the axis thereof and slidably iit within the cylinder. These baille plates 28 desirably are arranged at intervals with their adjacent edges overlap mg. It will,

however, be understood that t e baille plates instead of being formed on the piston, which is more convenient in construction, may be formed in the casing itself and it will also be understood that these baille plates instead of being arranged in lanes normal to the axis of the iston may e inclined relatively thereto within the spirit and scope of the invention.

By reason of this construction liquid entering through the inlet opening when the valve is removed from its seat will follow a s iral course along a portion of the length of the piston and being obstructed by the bailles will be divided into a plurality of sinuous streams the opposition and eddying of which will greatly reduce the flow under high pressures, while by reason of less interference and eddying under low pressure will ermit a relatively free flow of the liquid.) Thus asubstantially uniform discharge will be provided. The combined action of the spiral current and the divided current will cause the discharge of the liquid from the outlet pipe into thetank to be sul stantially noiseless under all pressures.

The present construction illustrated in Fig. 1 diiers mainly from the prior construction disclosed in my 1 atent aforesaid in that the spiral impetus o the current entering the chamber w11l increase the interference and eddyng of the liquid during its delivery through the ortion of the casing in whichjt is impeded y the alternately arranged baille plates, thus enabling the valve to be employed eifectually upon h1gher pressure 'systems without materially affecting its eilciency upon low pressure systems.

Theconstruction illustrated in Fig. LLmay lbe and preferabl is similar to that illus trated and descri d with respect to Figs. 1, 2 and 3 except thatadditional means are provided' for again modifying the /tlow of the li uid within the cylindrical casing and with t e further exception that a compound leverage mechanism 1s illustrated for actuating the piston.

In the construction illustrated in Fig. 4 the piston is provided with the s iral 27 and with the oppositely .disposed ba e` plates 28 arranged at intervals, as illustrated and described with respect to the construction shown in Figs. 1, 2 and 3. It is also rovided w1th a pair of baille plates 29 wiiich are oppositely disposed and have their adjacent edges in alinement, but spaced apart to provide passages for the liquid. It will be understood that any desirable number of pairs of baille plates may be employed. The adjacent edges 30 of the baille plates 29 desirably are arranged to present walls inclined to axial planes of the iston and preferably where a plurality o? such passages are provided in each set of annularly disposed baille plates the inclinations of the end walls of the baille plates are such as to cause the liquid delivered through the passag to il'ow in'spirals havin the same direction of movement so that w en the liquid is delivered into the enlarged outlet chamber 9 the streams will merge into a single stream having a centrifugal movement.

reason of this construction the ilow of B the liquid will be subjected to additional im-y pedance particularly where very high pressures are employed.

It will be understood that the invention contemplates the use of any combination of two or more of the means for modifying the flow of liquid through the casing as may be best adapted for the varying conditions under which the `valves are to be installed. There the ball-cock is used upon exceedingly high pressures it is desirable that. the compound leverage mechanism be employed for actuating the piston in order that the valve may be closed with certainty against such high pressure.

In the construction shown in Fig. 4 a preferred type of compound leverage system is illust-rate In this construction the upper end of the casing is provided with upwardly extending arms 31 and 32. fulcrumed upon trunnions 34 in the arm or arms 32 and preferably is provided with ya cylindrical portion 35 which engages the A lever 33 is filling of the tank after its discharge valve' is closed to complete the Water sealing of the trap from the ball after it has been emptied end of the piston. The lever 33 isA pivotally connected at its other end to a link 36 the opposite end of which link is pivotally con-4 nected to the arm 37 of a lever 38 which is lpivotally mounted on a. shaft or tiunnions 39 in the up er end of the arm 31, the lever 38 being secured to one end of the rod 17, the other end ofwhich is provided with the usual ball float. (not shown).

In usual types of ball-cocks an aperture is provided in the spherical portion of the casing to i'eceive a pipe leading to the delivery pipe of the tank for 'the purpose of supplying a sufficient amount of liquid during the b y siphoiiic action. ln the present coiistruo tion one side of the spherical portion of the casing' is provided with a b oss 40 having an aperture therethrough leading to the chamber 9, a. portion of which aperture entends upwardly and receives the .end ofl a pipe 41 leading t0 the delivery pipe of the tank. By reason of this construction the ball-cock is adapted to be placed more closely adJacent the wall of the tank and also presents a neater appearance. u

In the construction disclosed in Fig. 4c, as in that described in connection with Figs. 1, 2 and 3, the :means for impeding the flow of liquid through the casing may be formed upon the casing instead of upon the piston Within the spirit and sco-pe of the invention.
